GL Series Up per-plug/ Lower-plug Discharging Valve is a special single-seated control valve. The Y-type passage is treated by abrasion blasting and there is no blind corner and block in it. It is driven by AM8 series pneumatic diaphragm actuator or AH8 series pneumatic cylinder actuator. It is widely used in industry of fine chemicals, drug manufacturing etc. with the fluid which has granules in it or is easy to deposit. It is suitable for the working condition which has little space on radial direction under the reaction kettle.
